The lie detector returned and the girls are given the chance to quiz the boys.

And for Jack, things are made all the more awkward when he realises that his original flame, old Laura, will be asking questions set by current partner, New Laura.

New Laura immediately senses the unease that lies ahead: “I didn’t realise that Laura was going to be asking Jack the questions. The first thing that was going through my mind was ‘Laura, you idiot.’ I literally was just melting into the floor. How could you put the poor boy through this?

Relishing her role as question master, old Laura jokes to Jack: “Are you happy I’m doing your questions?”

Through gritted teeth, Jack responds: “Someone’s got to do it, might as well be you.”

In the first round, Jack confessed his head could be turned outside the villa.

As the questions then get underway, there’s immediate awkwardness when Laura asks: “Do you still have feelings for old Laura?”

Without hesitation, Jack replies “No," with the lie detector said was true.

This prompts Laura to mutter under her breath: “Did you ever? You said it really fast, d**k.”

Laura’s sass sparks gasps all round from the remaining Islanders, all of whom are observing from the lounge area.

Later in the Beach Hut, he vents: “I thought that was a bit of a low blow but whatever.”

There is then yet more discomfort when Laura asks: “Is new Laura a better kisser than old Laura?”

Staying loyal to his current squeeze, Jack insists “yes," which the lie detector said was true. He then added to old Laura: “I’m not saying you’re not a good kisser.”

Laura then flippantly remarks: “F**king ruthless. This isn’t about me, this is about you.”

The lie detector then said Jack was lying about wanting a long term relationship. 'Old Laura' quipped: "It’s fine. You’re young. You don’t know what you want.”

Next, the lie detector proved Jack was telling the truth about his kiss with Georgia.

There was then an awkward moment when Jack admitted he felt Laura wasn't the best looking in the villa and wasn't falling in love with her.
